The SPEEDHUB Oil Change Kit includes the following articles:
12,5ml All Season Oil / 25ml Cleaning Oil in a 50ml bottle
Oil filling tube
Oil drain screw
60ml syringe
Once annually or once every 5000km. That is the schedule in which your SPEEDHUB gear hub requires an oil change. The purpose of this is to ensure that any oil lost over the previous 12 months is replaced, and that any moisture which has penetrated the hub is rinsed back out.
If the SPEEDHUB never lost a drop of oil over the past 12 months, then the combined volume of oil inside the hub after the cleaning oil is added, will equate to approximately 37,5ml. The Cleaning Oil bottle can therefore accommodate this entire 50ml volume for easy disposal after extraction.
